Aldabra is the world's second-largest coral atoll. | WIKI |
Aldabra Atoll (Seychelles) | WIKI |
Historically, the name Aldabra was Al-Hadra or Al-Khadra (with several variants), given by Arab seafarers[2] for "the atollxe2x80x99s harsh, sun-baked environment"; this name was included in the Portuguese maps of the 16th century. | WIKI |
In the middle of the 18th century, the atoll became a dependency of the French colony of Rxc3xa9union, from where expeditions were made for the capture of the Aldabra giant tortoises. | WIKI |
[6] As there are no surface freshwater sources on Aldabra, the interests of the explorers (no proof of any explorer's visit prior to 1742) was only to exploit the species of tortoise, turtle and fish, and not to inhabit the atoll. | WIKI |
The exploitation of tortoises for commercial purposes at that time is borne out by the remnants of a crushing mill at Picard Island, which was used to crush bones of tortoises, which were also brought in from other islands in the atoll. | WIKI |
Efforts made to grow plantation crops of coconuts, cotton, and sisal failed due to inadequate water sources on the atoll; relics of these plantations are still found on some of the islands. | WIKI |
[3] Sailors landed on the atoll in the 19th century and attempted to raid the island for tortoises as food; in 1842, two ships were reported to have taken 1200 of them. | WIKI |
In the early 1800s, concessions given to individuals almost destroyed the forests and tortoise habitats in many islands in Seychelles; on Aldabra Atoll, in view of its remoteness and rugged topography, only small areas of forests were cleared for agricultural operations (mostly coconut plantations) but the tortoises were intensely captured for meat and trade. | WIKI |
[10] However, James Spurs, who had the concession of the atoll, was responsible initially for saving the tortoises on the atoll when he banned killing them in 1891. | WIKI |
Introduction of invasive species was banned, faunal species were protected under law, and active research on the ecology and biodiversity of the atoll was undertaken by the Royal Society of London from the middle of the 1970s. | WIKI |
The BBC were dependent upon the RAF for developing the atoll as without this their own ambitions would not have been feasible. | WIKI |
After an international protest by scientists (known as 'the Aldabra Affair'), however, the military plans were abandoned and the atoll instead received full protection. | WIKI |
Subsequent to the thwarting of plans to establish a military station at Aldabra (which instead focused on Diego Garcia in the Chagos Islands), the Royal Society of London resumed their scientific study of the flora and fauna of the atoll with Professor David Stoddart as the leader. | WIKI |
The Royal Society bought the lease of the atoll in 1970 and their research station became functional from 1970. | WIKI |
After completion of their assigned work, the Royal Society left and the Seychelles Island Foundation (SIF), a public trust of Seychelles, took over the management and protection of the atoll in 1979. | WIKI |
A brass plaque inscribed with the citation "Aldabra, wonder of nature given to humanity by the people of the Republic of Seychelles" is stationed on the atoll. | WIKI |
This appreciation befits the atoll which is truly one of the greatest ecologically undisturbed raised coral atolls in the world. | WIKI |
Aldabra atoll is in the most southwesterly part of the Seychelles, and is closer to the coast of Africa 630xc2xa0km (390xc2xa0mi) than to Mahxc3xa9. | WIKI |
The atoll is the largest raised coral reef in the world with an elevation of 8 metres (26xc2xa0ft); and the second-largest atoll in the world after Kiritimati Atoll. | WIKI |
[16] Aldabra atoll is 34 kilometres (21xc2xa0mi) long (in eastxe2x80x93west direction) and 13 kilometres (8.1xc2xa0mi) wide. | WIKI |
[6] Around the rim of the lagoon are the larger islands of the Atoll. | WIKI |
The total land area of the Atoll is 155.4 square kilometres (60.0xc2xa0sqxc2xa0mi). | WIKI |
The outside rim of the atoll has three passages which connect to the lagoon, which is 6xe2x80x9310 kilometres (3.7xe2x80x936.2xc2xa0mi) in width as it opens to the sea. | WIKI |
Aldabra atoll has, besides the four larger islands, some 40 smaller islands and rocks,[19] all inside the lagoon, as well as a few very small islets at the West Channels between Grand Terre Island and Picard Islands, the largest of those being xc3x8elot Magnan. | WIKI |

The atoll reflects both fossil and geomorphological features, the former is the source of the biodiversity seen today. | WIKI |
[22] The atoll is made of reef limestone of Pleistocene age (with irregular coral formations called "champignon",[23] made up of two layers of varying stages of crystallization [24]) and this extends over an average width of 2 kilometres (1.2xc2xa0mi) rising to a height of 8 metres (26xc2xa0ft) above sea level, and forming the rim line (low cliffs with "deep notches, preceded by jagged pinnacles") of the shallow central lagoon. | WIKI |
There have been recorded 273 species of flowering plants, shrubs, and ferns on the atoll. | WIKI |
The atoll has distinctive fauna including the largest population of giant tortoises (Aldabrachelys gigantea) in the world (100,000 animals). | WIKI |
[33][34] Tortoise size varies substantially across the atoll, but adult tortoises typically have a carapace length of about 105 centimetres (41xc2xa0in) and can weigh up to 350 kilograms (770xc2xa0lb). | WIKI |
Conservationists feared a major threat to the atoll's biodiversity in the 1960s when, as part of the British Indian Ocean Territory, the British made plans to set up a military establishment on the atoll. | WIKI |
Invasive alien species such as rats, cats and goats that were introduced in the past threaten the native biodiversity of the atoll. | WIKI |
Goats were eradicated from the atoll in 2012 after a long-term eradication program. | WIKI |
Research into a feasibility study to eradicate rats from the atoll has been undertaken. | WIKI |
Due to the limited space of its habitat, extreme weather conditions, epidemic and limited range could also pose serious threats to the entire ecology of the atoll. | WIKI |
Aldabra atoll was designated a UNESCO World Heritage Site on 19 November 1982. it is one of the two UNESCO World Heritage Sites in the Seychellesxc2xa0;,[54] and is managed and protected by the Seychelles Islands Foundation (SIF). | WIKI |
[6] Based on the evaluation process, UNESCO inscribed the site, a legally protected special reserve of 35,000 hectares (86,000 acres), on the list of World Heritage Sites under three criteria: Criterion (vii): Aldabra Atoll encompasses a large expanse of relatively untouched natural beauty where a number of important animal species and some plant species thrive, along with remarkable land formations, and its process provides a unique spectacle of natural phenomena;[6] Criterion (ix): The atoll is a superlative example of an oceanic island ecosystem in which evolutionary processes are active within a rich biota. | WIKI |
The size and morphological diversity of the atoll has permitted the development of a variety of discrete insular communities with a high incidence of endemicity among the constituent species that are typical of island ecosystems. | WIKI |
The atoll constitutes a refuge harboring viable populations of a range of rare and endangered species of plants and animals. | WIKI |
BirdLife International declared Aldabra as an Important Endemic Bird Area (IBA) in 2001 on account of its large seabird colonies under categories A1, A2, A4i, A4ii and A4iii, covering an area of 33,180 hectares (82,000 acres) overlapping with the special reserve area of 35,000 hectares (86,000 acres) of Aldabra Atoll. | WIKI |
[14] Covering 25,100 ha (over half the area of the whole atoll) the wetland ecosystem of Aldabra include the extensive shallow lagoon inside the atoll, which is carpeted with lush seagrass beds and patchy coral reefs, the intertidal mud flats, the coral reefs outside the lagoon, freshwater pools, beaches, and 2000xc2xa0ha of mangrove stands. | WIKI |
These wetlands support several endangered species including the increasing number of turtles at the atoll, dugongs and many other bird, fish and invertebrate species. | WIKI |
No airstrips, helipads or landing jetties have been permitted to be built on the atoll. | WIKI |
Cruises are operated by several companies [59][60] along with dive boats which may visit the atoll on expedition tours. | WIKI |
[59] As of 2012[update], an average of 900 tourists visit the atoll a year. | WIKI |
Within the atoll, paved walking paths exist from the village of La Gigi, which leads to a promontory from where scenic views of the large lagoon (during low tides) and the mangrove species are seen. | WIKI |

Located in the Indian Ocean, the Aldabra Atoll is an outstanding example of a raised coral atoll. | UNESCO |
Due to its remoteness and inaccessibility, the atoll has remained largely untouched by humans for the majority of its existence. | UNESCO |
The richness and diversity of the ocean and landscapes result in an array of colours and formations that contribute to the atoll's scenic and aesthetic appeal. | UNESCO |
Criterion (vii): Aldabra Atoll consists of four main islands of coral limestone separated by narrow passes and enclosing a large shallow lagoon, providing a superlative spectacle of natural phenomena. | UNESCO |
The lagoon contains many smaller islands and the entire atoll is surrounded by an outer fringing reef. | UNESCO |
The size and morphological diversity of the atoll has permitted the development of a variety of discrete insular communities with a high incidence of endemicity among the constituent species. | UNESCO |
The atoll's isolation has also allowed the evolution of endemic flora and fauna. | UNESCO |
The atoll constitutes a refuge for over 400 endemic species and subspecies (including vertebrates, invertebrates and plants). | UNESCO |
The property includes the four main islands which form the atoll plus numerous islets and the surrounding marine area. | UNESCO |
It is sufficiently large to support all ongoing biological and ecological processes essential for ensuring continued evolution in the atoll. | UNESCO |
The remoteness and inaccessibility of the atoll limit extensive human interference which could otherwise jeopardize ongoing processes. | UNESCO |
